IMPROVEMENT IN CCRN-SHELLIN-G MACHINES.

VSpecifiozzation forming part of Letters Patent No. 193,130, dated July 17, 1877; application filed May 12, 1876.

To all whom z'tmay concern:

Be it known that I, G. D. READ, of Ayer, county of Middlesex, State of Massachusetts, have invented a new and useful Improvement in Centering Device for Gorn-Shellers, or for any similar purpose for which entering to a center is the desired object, which improvement is fully set forth in the following specication, reference being had to the accompanying drawings- Figure l being a side view of the centering device; Fig. 2, a top view, the ring partially broken away to show the lugs Gr; Fig. 3, a bottom view, looking upward; Fig. 4, a central vertical section thereof.

Like letters designate corresponding parts in all of the figures.

The special purpose of my invention is to be applied to cornshellers, and more especially to the one patented by C. D. and E. D. Read, July 27, 1875, No. 166,142.

The nature of my invention consists in various improvements in the construction and functional parts of the device, and I will set forth the said improvements one by one in succession.

` First, in the construction of the hopper or body on which the several working parts are mounted, the hopper or body a thereof consists of a short upright cylindrical. flanged casting, with lugs G cast on its outer circum-A ference for the guidance of ring B, and the support of the wingplates C C G C and coiled springs D D, the wing-plates being pivoted thereto on the screws or pivots e e.

Ring B is cast with downward projections, resting on the flange of hopper a, and an inward flange and short studs F F F F on the upper side. The inward liange of ring B rests against shoulders on the guide-lugs of hopper a, to hold it in position and to allow it 'to move freely, it being pressed back and.

held in position by the two coiled springs D D.

The four wing-plates are pivoted to the hopper by the screws or pivots e e, and are slotted at their outer ends to connect with the movable ring by the upward-projecting studs F F F F, and are provided with upward, inward, and downward projections, with inclined Vs on the inner surface of the projections, to prevent the ear from turning,

and allow it to enter with greater ease. These wing-plates are pressed toward one another, and the central space between them, by means of the coiled springs D D, resting on their ends against the lugs G of hopper a, and corresponding projections cast on the inside of ring B, or any equivalent of springs may be employed; and in order that these wing-plates may press equally and move vsimultaneously with 'equal motion, so as to keep the middle space between them always central, I provide them with a slot in their outer ends, and connect them to the corresponding studs on ringv B, so that neither wing-plate can move without acting by said slot and stud to move the ring B, and thereby moving the others equally and simultaneously.

The object of my invention is to enter centrally the ear of corn in a corn-Sheller, guiding it direct to the shelling-points, and holding it with the assistance of the shelling arms androlls below in a vertical position until it has passed through.

Having thus described my invention, what I claim as my invention, and desire to secure by Letters Patent, is-

' 1. The hopper a, formed with a short upright cylinder, with lugs G cast on its outer circumference, and acircular bottom dan ge arranged for the support of ring B and wingplates G (l C G, substantially as and for the purpose specified.

- 2. The movablering, with its upward-projecting studs F F F F, or their equivalents, connecting with the wing-plates C' G (l (l, in combination withthe coiled springs D D, substantially as specied.

3. The wing-plates C C C C, pivoted to the hopper c, and connected by their slotted ends to the movable ring B, and provided with upward, inward, and downward projections, with inclined Vs on their inner surfaces, constructed and arranged to operate substantially as and for the purpose herein specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
